PTEROSTICHIN.E 333 



9.5 mm.; width 3.6 mm. A single specimen, unlabeled in the Levette 

 collection but probably from Colorado. 



This very small species also belongs to the same section as the 

 two preceding and longulus, but it is more abbreviated and with 

 shorter and more oblong-oval elytra, the latter relatively wider 

 when compared with the prothorax; the base of the latter is not 

 yery obviously narrower than the apex. 



In the three preceding species I can find no trace of the ocellate 

 puncture of the scutellar stria, which is usually visible throughout 

 the genus Hypherpes; it is probably also wanting in longulus. 



Hypherpes intectus n. sp. Form rather narrow and elongate, black, 

 shining, the elytra strongly alutaceous in the male; legs and tarsi black, 

 the anterior tarsi (cf) piceous; head moderate, slightly elongate, almost 

 two-thirds as wide as the prothorax; eyes moderate, prominent, the sulci 

 feebly arcuate, separated by a third the interocular width; antennae fusco- 

 ferruginous throughout; prothorax large, a fifth or sixth wider than long, 

 widest near apical fourth, with the sides moderately reflexed, evenly and 

 moderately rounded anteriorly, straighter and oblique basally and moder- 

 ately reflexed, scarcely visibly sinuate toward the basal angles, which are 

 obtuse, slightly blunt and not prominent; base scarcely sinuate medially, 

 margined laterally and distinctly narrower than the moderately sinuate 

 apex, the rather prominent apical angles blunt at tip; impressions both 

 obvious; inner fovea long, broadly and moderately impressed, the outer 

 very short, feebly impressed, the carina wanting; surface outside of the 

 inner fovea flattened; elytra nearly four-fifths longer than wide, a fifth 

 wider than the prothorax, regularly rounding at tip, the parallel sides 

 broadly arcuate, rounding more at base, the sinus feeble though evident, 

 the humeral denticles subobsolete; striae rather fine but well impressed, 

 impunctate, the scutellar short and oblique, the ocellate puncture small, 

 adjoining the second stria; intervals broadly though evidently convex. 

 Length (cf ) 14.0-14.2 mm.; width 4.6-4^ mm. Colorado (Boulder Co.). 



Allied somewhat to occultus, from northern California, but lar- 

 ger, with more evident outer thoracic fovea and basally much less 

 sinuate sides, with less fine and much more impressed elytral striae 

 and convex intervals; in occultus the intervals are flat. 



Hypherpes vivax n. sp. Similarly elongate, rather narrow and moder- 

 ately convex, deep black, shining, the elytra (d 71 ) not dull though strongly 

 micro-reticulate; legs as in intectus; head moderate, slightly elongate, 

 nearly two-thirds as wide as the prothorax, the eyes very moderate but 

 prominent; sulci strongly converging and arcuate; antennae fusco-ferru- 

 ginous, the first joint nearly black; prothorax scarcely visibly wider than 

 long, widest anteriorly, the sides broadly, feebly rounded, slightly con- 

 verging though only straight basally, moderately reflexed; base trans- 

 verse, margined laterally, with the angles obtuse but unrounded at tip,
